Here's my daily driver and also my autocross car - '87 Honda CRX Si.  At 1,800 lbs and with a 1.5L engine I get pretty good mileage of 32 city/44 hwy.  Plus it's fun to drive!  Unfortunately the hot California sun is ruining the paint and the car's starting to look like a POS.  I understand having a beater car as a DD, but I'm hoping to upgrade to a nice, used Audi TT within the next couple of years.
The car's got everything done to it - four sets of wheels, full adjustable suspension, full exhaust, intake, port & polished head, ported throttle body, stripped interior, race seat/harness, etc.
